Not sure if this is a normal way to use these cores as i have no knowledge about it. But i came up with a way to get 2 isolated outputs from 1 input. The input windings go in the middle so from hole to hole and the 2 other windings are on the sides. This specific core gave 5.4v on output with 5v input but it was just put together with scraps to see if it works and it did really well.
